Integers & Order of Operations Help Fun Game Tips: - Adding positive and negative integers can be compared to winning and losing money. - A win of $4 added to a loss of $6 results in a total loss of $2. That is (+4)+(-6)=(-2). - To subtract an integer, you can add its opposite. - That means (-3)-(+7) is the same as (-3)+(-7) = -10. - Also (6)-(-2) is the same as (+6)+(+2)=8, because removing a $2 loss gives a $2 gain. - When multiplying 2 integers having the same sign, the result is positive. Example (-4)(-5)= 20. - When multiplying 2 integers having different sign, the result is negative. Example (-3)(+6)= -18. - The positive and negative sign rules for integer division are the same as for integer multiplication. - The order of operations requires that bracket operations be done before the 4 basic operations. - As a general rule, when several of the 4 basic operations occur in succession, do multiplication and division first (from left to right) followed by addition and subtraction (from left to right). - It may take a minute to load the game at dial-up speeds. - The game can be played using the mouse by itself or using the keyboard by itself. - If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus. - The game speeds up as your score increases. Adjust this with the - and + keys. |
